Shells, sub-shells and orbitals

What is the max amount of electrons on each shell?

1st = 2e-

2nd = 8e-

3rd = 18e-

4th = 32e-

What are the names of the orbitals?

S,P,D,F

What are the shapes of the S and P orbitals?

S-orbital = spherical shape

P-orbital = dumbbell shape

What makes up the sub-shells?

S-subshell = 2e- (1 s-orbital)

P-subshell = 6e- (3 p-orbital)

D-subshell = 10e- (5 d-orbitals)

F-subshell = 14e- (7 f-orbitals)

How many electrons do each orbitals hold?

Each orbital holds two, BUT they only group with ones alike.

What makes up the shells?

As the shells get further, 1st to 2nd to 3rd to 4th. They increase with the amount of sub-shells they hold.

E.g 1st = s-subshell 2nd = s and p subshell

Orbital meaning?

A region around the nucleus that can hold two electrons, with opposite spin.
